Comment (by juga):

 With a separate python script, i've collected descriptors' bandwidth
 during 3 days, every hour.
 I've tried the method you proposed, but it still don't smooth out spikes.
 I'm quite sure it's because the descriptors' bandwidth don't change
 (much).

 I assumed Torflow's `desc_bw` and `avg_desc_bw` are the descriptor
 `average bandwidth`, but looking TorCtl.py [0] seems to be `observed
 bandwidth`, so i'm going to collect those instead and see how that change
 the curve.

 In any case, if Torflow is applying a decaying average, do you know where
 is that in the code?.
